White Banded Awl (Hasora taminatus taminatus)

Rather uncommon* butterfly flies all the year round in dry and intermediate zone forests, mainly in the southeastern part of the country. The larva of White Banded Awl feeds on the leaves of Derris scandens and Derris parviflora. 

* However W. Ormiston wrote in 1924 "They suddenly appears in great numbers, generally during the north-east monsoon, and I am of opinion that they "flight." In October, 1916, I noticed great flights of large Hesperiidae on several evenings just before dark, all going south....Both [White Banded Awl & Common Banded Awl] are extremely plentiful all over Uva, up to the highest elevations, and I have specimens ..from Kandy and Deniyaya"

And L.G.O. Woodhouse noted in 1949 " Both species [White Banded Awl & Common Banded Awl] fly together; they suddenly appears in numbers generally during the north-east monsoon (October-December) and appears to be "flighting'...but can be taken in most months of the year, all over the island, particularly in the wet and hill zones, being comparatively scarcer in the low-country dry zone"
